Dara makes and sells n bracelets. Her profit in January is represented by the expression 2n-10. Her profit in February is represented by the
expression 5n + 12. Her profit in March is represented by the expression in -
6. Write and simplify an expression that represents her total profit for these
three months. What was Dara's profit if she sold 50 bracelets during that
time?

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
